WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 436,291, dated September 9, 1890.

Application tiled April 14, 1890. Serial No. 347,913. (No model.) Patented in Canada June 7, 1887, No. 26,904.

To @ZZ whom it may con/cern:

Beit known that I, ADOLPHE PATRICK, a citizen of Canada, residin'g at Maskinong, in the county of Maskinong and Province of Quebec, have invented certain new and useful Improvements in WaterVheels, (for which I have obtained a patent in Canada, No. 26,904., bearing date June 7, 1887,) of which the following is a specification.

My invention relates to improvements in turbine water-wheels in which a horizontally-revolving wheel rotates on a vertical axis; and the objects of my invention are, first, to secure the largest possible percentage of power by regulating the flow of the water in such a manner as to utilize all its volume and its greatest obtainable force, and, second, to produce at a comparativclysmall cost awheel that will be simple in construction, not liable to easily get out of order, and at the same time economical in the use of water. I attain these objects by means of the wheel illustrated in the accompanying drawings, in which- Figure 1 is a si de elevation of the wheel and case complete. Fig. 2 is a plan view of the same. Fig. 3 is a vertical section on the line oc w, and Fig. 4 is a horizontal section on the line y y.

In this wheel the principle of outward horizontal discharge is combined with an upward discharge, and to this end the water is conducted into the inner or central portion of the wheel, whence it liiows between iixed partitions and intermediate regulating-gates, by which it is directed against the buckets of the wheel immediately outside of said guides. The wheel is support-ed by a pivot fixed centrally in the frame, which carries both the wheel-case and the penstock, which is attached to it, all as hereinafter more fully described.

The pivot A, upon which the Wheel-shaft stands, is centered in the spider-frame C, the arms a of which extend outwardly to the ringplate r', upon which stand the arms g., exa tending upwardly to support another ringplate c. The two ring-plates r and c are bolted onto the arms a and g. The wheel case, by its iange b', rests on the ring-plate c. The floor D of the case has a raised cen tral boss, through which an opening is made for the passage of the wheel-shaft B through it. A sleeve E stands on and is secured to this boss by a water-tight joint and extends some distance up around the shaft, where it terminates in the packing-box i', which forms a close-fitting joint around the wheel-shaft and serves to steady the shaft in its upright position. A vertical wall F is formed on the inf4 ner edge or as a part of the ilange b and forms 6o whichit is strongly secured. The water issues from the case to the wheel between the flange G and the case-floor D. Its angular direction is controlled by the partitions d', which are curved in such a manner as to direct the water most advantageously. The regulating- 7o gates H, which are also curved like the partitions d', regulate the iiow of the water to the wheel. They are journaled both in the floor D and the flange G, and are operated in the following manner: The lower inside corners of the regulating-gates are provided with downwardly-projecting pins e', which are made to slide in grooves n cut into the lower extremity of a tube I. The tube I is made to turn around the sleeve E, and its 8o lower end opens so as to fit over the central boss of the floor D. On the outer end of an arm h', which is rigidly fixed to the upper part of the tube I, is a segmental rack f',

which is moved by a pinion j on a shaft k passing up to the mill-floor, where i-t may be turned by means of a crank or hand-wheel, and thus the gates II may be opened or closed at will. This mode of regulating the flow of water onto the buckets of the wheel is simple `9o and avoids all interfering mechanism and gives the way clear to the water from the penstock into the wheel-case, whence it iiows out between the partitions and the regulatinggates onto the buckets of the wheel. The wheel well keyed to the shaft B, radiate arms, roo

which carry the bottom ring K. The upright buckets L are cast on or attached to this ring and support the middle ring M, on the outer edge of which the outer wall N is formed. The upward discharge-buckets O are secured to or formed on both the middle ring M and the outer wall N. The iirst impulse of the water on the buckets O is upon that portion of the bucket which is close to the middle ring M, after which the crowding of the water against the sloping wing helps to lift the weight of the wheel 01T the pivot A. The action of the water on the upright buckets L is rst against their inner portions, which are at nearly right angles with the direction of the water coming from the case between the guides d', and afterward by itsv centrifugal force against the sloping wings of the buckets. y

I am aware that water-wheels have been made with wicket-gates devised for the purpose of regulating the iiow of the water onto the buckets of the wheel. I therefore do not claim such a combination, broadly; but

What I claim as my invent-ion, and desire to secure by Letters Patent, is-

l. In a turbine water-wheel, the stationary central wheel-case, in combination with the wheel having the series of side dischargebuckets L thereon in communication with the case and the series of upward dischargebuckets O, located above the buckets L and also in communication with the case, and the walls M separating said series of buckets, whereby the wat-cr issuing from the wheelcase has an outward impact on the buckets L to revolve the wheel and an upward impact on the buckets O to assist in sustaining the weight 'of the wheel.

2. The combination of the central Wheelcase provided with partitions for defiecting the water, the wheel having the series of outward discharge-buckets L, closed at the top and bottom, and the series of upward discharge-buckets O, located above the buckets L and closed at the under and outer side, both of said series of buckets surrounding the wheel-case and in communication therewith.

3. In a turbine Water-Wheel, the c0mbination, with the stationary central wheel-case provided with partitions and intermediate regulating-gates for deiecting the water and in communication therewith, of the gate-regu lating tube I, extending downwardly to the bottom of the wheel-case, with grooves n cut at its lower end to receive the pins e', and at the upper end of which is rigidly xed the arm h, connected with suitable mechanism for turning said tube when so arranged and constructed as to open or close the regulating-gates A from under by the simple turning of the tube I, as and for the purpose set forth.
